i This invention relates the shoe herein illustrated being of the platform type. a

An object of this invention isto provide a durable and comfortableshoe of this type.

In making the shoe of the present invention, an insole of the shapea'ndsubstantially the size toplatform type shoes,

ce ses fina e upon the bottornpf theiplat- .formy,

Fig. is a sectional, detail of a .shoe after attachmentof theoutsolepand Fig. 6 is aside elevation of a completed shoe.

In making the shoe, an insole I'D of the shape j and substantiallyof'the .size of thefllast bottom of the last bottom is made and covered on its inner face with sock-lining material,- the mate- .rial being out enough larger thanthe insole so that the material, when laida'cr'ossthe edge face of. the insole, will project a'substantial distance beyond its outer face. The outer face of the insole is covered with a similar but somewhat smaller piece of material which may be, for example, Gem duck. These coverings are cemented, respectively, to the inner and outer faces of the insole, the marginal portions of the larger piece covering the inner face of the insole being laid across and cemented to the edge face of the insole, the portion projecting beyond the outer face of the insole being cemented to the marginal portion of the outer covering of the insole. about the periphery of the insole is formed an upstanding rib composed of two layers of material cemented together.

The insole thus prepared is assembled with an upper upon a last and the upper lasted in a usual manner, for example with tacks or staples. As illustrated, the upper is tensioned and secured in lasted position by tacks driven through the upper and rib into the insole.

The shoe may now be presented to an inseam sewing machine provided with a guide for a platform-cover strip, the cover strip, upper and rib of the insole being sewed together by a seam located at the base of the rib. The inseam may be trimmed and a platform sole laid on the shoe bottom, the platform being preferably the size of the shoe bottom including the seam. The platform-cover strip is laid over and secured, for example by cement, to the bottom of the platform, and an outsole cement-attachedto the overlaid cover. As illustrated, the platform includes a wedge heel which also is covered by the cover strip.

is prepared. Since the'insole is to be completely covered, a wide variety of materials maybeused. To enhancethe comfort of the shoe; however, it is desirable, to use acushion material such as felt for the insole. An inner coyer orsock. lining i2 and an outer cover or reinforcement. are provided, the cover 12 being largerthan the insole by the thickness of the insole plus the height of a usual sewing rib. The outer cover I4 is larger than the insole by the height of the sewing rib. The cover I4, since it is hidden in the completed shoe, may be of any strong fabric, such as Gem duck, or may be of the same material as the cover 12.

The cover I2 is cemented to the inner face of the insole In and to its edge face, its marginal portion being allowed to extend perpendicular to the outer face of the insole at least to the height of a usual sewing rib. The layer I4 is cemented to the outer face of the insole, and its marginal portion is cemented to the upstanding portion of the cover i2, thus forming a two-ply rib l6 about the periphery of the insole, a crosssection of the insole then appearing as shown in Fi 1.

The prepared insole is secured to the bottom of a last [8, for example by tacks 20 (Fig. 3 and an upper 22 is assembled on the last. The upper is tensioned and secured in lasted position in any usual manner, for example by staples or by tacks 2 .1 driven through the upper 22 and rib I 6 and into the insole Iii, as shown in Fig. 2. The shoe is next presented to a sewing machine, for example an inseam sewin machine such as that disclosed in United States Letters Patent No. 1,108,560, granted August 25, 1914, upon an application of Andrew Eppler, the machine being provided with a suitable guide for a platform cover strip 26 so thatthe cover strip is included in the seam 28 which also connects the upper 22 and the rib I6, as shown in Fig. 3. The inseam may now be trimmed but not so close as to endanger the strength of the inseam. The platform sole 30 is laid on the shoe bottom, as shown in Fig. 4, the platform sole being preferably of the size of the insole plus the thickness of the cover l2, the upper 22 and the platform cover 24. Since platform soles are usually of yielding material such as felt, they can be compressed sufficiently in the platform laying operation to accommodate the inseam, though the margin of the platform may be reduced or rabbeted in the region of the inseam if desired. The cover 26 is laid over and secured, for example by cement, to the bottom of the platform, as illustrated in Fig. 4. A usual heel wedge may lie-attached to the 'plat'formhnd covered by the platform cover 26 whichis, or course, in that case made wider at the shank and heel to cover also the wedge heel.

An outsole 32 is attached, as illusfirated iii Fig.

sole and having their marginal portions united to constitute an upstanding sewing rib about the periphery of the insole, the upper and platform cover being sewed to said rib, the marginal portions of the platform cover extending over the marginal portion of the bottom of the platform, and said outs'ole being cement-attached to the marginal portion of the platform cover.

3. 'A platform shoe' having an upper, an insole, a platform sole, a platform cover and an outsole, said insole having covers on its inner and outer "faces, said covers being larger than the insole 5, and may as usual be cement attac hed to the overlaid portion of the cover strip 26.
